Which of the following statements best describes Category I fetal tracing?

• A. Category II normal
• B. Category I normal
• C. Category III abnormal
• D. Category I abnormal

Answer: (B)

Category I fetal tracing is normal and reassuring. It typically shows a baseline fetal heart rate in the normal range (about 110–160 bpm), with moderate variability, and no late or variable decelerations. Accelerations may be present, and early decelerations can occur and are benign. This combination indicates adequate placental function and fetal oxygenation, so there’s low risk of fetal distress and routine labor management with ongoing monitoring is appropriate. In contrast, indeterminate patterns (Category II) require closer surveillance, and abnormal patterns (Category III) with features like recurrent late decelerations or absent variability indicate potential fetal hypoxia needing urgent intervention.
